Patented July 19, 1932 UNITED STATES JACK OSTER, OF GREELEY, COLORADO GRAIN- SAVING ATTACHMENT FOR BINDERS AND HARVESTERS Application filed December 27, 1930. Serial No. 505,160.

The present invention relates to improvements in binders and harvesters and more particularly to means for saving grain which I is lost as the result of the movement of the grain stalks through the machine.

An object of this invention is to provide a simple grain saving device which may be readily mounted on threshers and binders of various types without interfering with the w operation of the presentparts of the machine.

Another object of this invention is to provide a grain saving attachment which is so constructed that the grain receiver may be readily removed whenv it has become filled .o' with grain.

A further object of this invention is to provide a grain saver which is so constructed as to accumulate at one point grain which has dropped or become loosenedfrom the heads wj' as the cut stalks and heads are moved through the machine, the device being positioned at the discharge end'of the binder.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings wherein Figure 1 is a fragmentary detail side elevation' of a conventional binder having mounted thereon a device constructed according to the preferred embodiment of this invention;

Figure 2 is a detail top plan View of the device;

Figure 3 isa detailside elevation of the device;

Figure 4 is a transverse section taken on the line 44 of Figure 3; and

Figure 5 is a fragmentary detail end elevation of the device showing the manner of releasably securing the grain receiver in the supporting frame. I

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral designates generally a binder of conventional construction which is provided withanelevator 11 and a binding platform 12. The grain which is cut by the binder is adapted to be carried along the elevator 11 and passed to the binding platform 12 where the grain is made up into bundles by the conventional bundle tying apparatus.

The threshing machine 10 is also provided with a rockable discharge member 13 at one end thereof which is adapted to be released intermittently for discharge of the bundles of grain which are dropped thereon from the bundle tying platform 12. The movement of the grain as it passes up the elevator 11 and onto the bundle tying platform 12 is such as to shake out a considerable quantity of grain from the heads of the stalks and this grain is usually dropped through the space 14: between the upper end of the elevator 11 and the inner end of the platform 12. The grain is also lost from the bundle tying platform 12 due to the handling of the stalks and heads by the bundle tying apparatus, and the grain drops off of the outer end of the platform 12 and onto the ground as the bundle drops onto the discharge member 13.

In order to save the grain which is usually lost at theinner and outer ends of the bundle tying platform 12 and along the surface of the bundle tying platform 12, it being understood that the platform 12 is usually of split construction having a longitudinally disposed slot therein through which a considerable quantity of grain usually falls onto the ground I have provided an elongated chute 15. The upper end of the chute 15 is adapted to be positioned closely adjacent the under side of the elevator 11 so that as the elevator rotates or travels along the grain from the upper surface of the elevator will be discharged onto the upper end of the grain saving chute 15.

A supporting frame generally designated as 16 which is adapted to removably receive a grain hopper generally designated as 17 is mounted within the binder 10 in such a position as to receive the grain which gravitates downwardly onto the upper surface of the chute 15. The supporting frame 16 comprises a pair of upper longitudinally disposed side members 18 and a pair of lower side members 19 Which are secured to the frame of the binder 10 by means of aplurality of spaced straps 20; A plurality of transversely disposed bottom members 21 are secured to the frame 17 and adapted to hold the side members 18 and 19 in spaced relation to each other. The frame 16 is also provided with end straps 22 which are placed across the end of the frame 16 so as to limit the insertion of the grain hopper 17 within the frame 16.

The hopper 17 comprises a substantially rectangular shapedmemberwhich is open at the upper surface thereof and is provided at one end with a handle 23 so as to permit the withdrawal of the hopper 17 from the frame 16. The bottom of the hopper 17 is adapted to slidably engage the transverse members 21. Ifdesired, the bottom members 19 may be constructed in substantially L shaped form so as'to provide a guide track for slidably' receiving the bottom of the hopper 17. A rockable locking member generally designated as 2 1 is secured to one end of the frame 16 and engages one end of the hopper 17 so as to releasably securethe hopper 17 within the frame 16. The locking member 24 comprises a transversely disposed bar 25 which is provided with L shaped opposite end portions 26 through which a pivotal member 27 is adapted to pass,'the pivotal member 27 being secured to the frame 16 so as to rockably position the locking member 24: within the frame 16. The locking member 24 is also provided with a'looped handle 28 which is secured to a pair of depending straps or arms 29 Car ried by the transverse bar 25' intermediate the ends thereof. i o

The binder 10 is also provided with a second chute 30 which is positioned on the frame of the binder at the discharge end of the binding platform 12 and is positioned in spaced relation to the outer end of the platform so that any grain carried downwardly on the inclined surface of the platform 12 will strike the'baffleplate 30 and be directed downwardly into the hopper or receiving member'17. i

The hopper 17 is also provided with a transversely disposed bar 31 which is positioned within the hopper 17 intermediate the ends thereof and closely adjacent the inner end.

. While there have been disclosed a pair of baffle plates 15 and 30 positioned within the body of the binder 10 I do not wish to be limitedto the number of these plates as the number will vary accordingto the construction of the hinder or thresher. Furthermore, in threshers of varying sizes it may be expedient to position a number or plurality of frame members 16 and hoppers17 at convenient points within the frame 10 of the thresher or binder so that substantially all not discharged onto the ground due to the rough handling there of by the hinder or thresher.

In the use of this device, the frame 16 is adapted to be positioned at a convenient point within the frame 10 of the binder or thresher and the battle plates 15 and 30 so mounted as to receive the grain from the elevator 11 and the bundle tying platform 12. The hopper or grain receiving member 17 may be of any desired length and is preferably of a length sufficient to extend the full width of the platform 12and coactively the frame 16 is of a similar length. I

When the binder 10 is placed in operation, the grain passing upwardly on the elevator 11 and becoming'loosened from the heads of the stalks will drop onto the first bafiie plate 15' and pass downwardly thereon into the hopper 17 Any grain which becomes loosened from the heads during the bundle tying operation 'will pass downwardly on the inclined tying platform 12 and strike the seo- 0nd baffle plate 30 from whichpoint they will pass downwardly and forwardly into the hopper 17 T When the hopper 17 becomes substantially filled, the rockable locking member 24 may be swung upwardlyand the hopper 17 pulled outwardly of the frame 16 by means of the handle 23. It will be obvious from the foregoing that a relatively simple and at the same time practical grain saver has been devised which is so constructed as to not interfere with any of the present parts of the binder or thresher but which will accumulate at one point a considerable quantity of grain which is at the present time dropped onto the ground. I

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof,'such changes and modifications being restricted only by the scope of thefollowing claims.

What is claimed is 1. In a grain harvesting and binding machine, a grain saving attachment comprising a frame, a hopper disposed within the frame, and means for releasably securing the hopper in the frame.
